Why are there white smoke pouring from the pipes of the supermarket's vegetable shelves
Is water mist, in the supermarket equipment is fully automatic spray fresh shelves, are generally directly with tap water. Mainly for vegetables add moisture to prevent dehydration, achieve the goal of keeping fresh
In the mall, there should be water, a reason for the humidifier, to keep the vegetables fresh
That's a shelf with a wet function with fruit and vegetables. He sprayed the mist (that is, water vapour) to keep the vegetables wet, and wouldn't wither and cause the selling to be bad.
